| 摘要 |
The present invention relates to a method and to plant for joining together a first tubular bobbin section (1) produced from wound paper or like material and having a circular cross section whose outer diameter is much greater than the wall thickness of the bobbin section, to a corresponding second bobbin section (2). The end-related and outer edge-region of one bobbin section (1) is worked to a frusto-conical shape which is convergent from the one bobbin section. The end-related and inner edge-region (2b) of the other bobbin section (2) is worked to a corresponding frusto-conical shape which is convergent inwardly to the other bobbin section. An outer, and/or an inner part of respective edge-regions is given a respective edge (1c, 2c) and these edges are orientated for mutual supportive coaction when the bobbin sections (1, 2) are pressed together, after having applied the adhesive substance to one or both of the worked surfaces. |
